PAPER CARRYING AND FEEDING ATTACHMENT FOR ADDING-MACHINES.

SPECIFICATION forming part Of Letters Patent N0. 648.708, dated by 1, 1900.

Application filed September 26,1899- Serinl In. 731,728. Ho model.)

To all whont it may concern:

Be it known that I, Comvm II. PLA'rr, a citizen of the United States of America, residing at Cleveland, in the county. of Cuynhoga and State of Ohio, have invented a. certain new and useful Improvement. in Paper Carrying and Feeding Attachments for Adding- Machines, of which the following is a description, reference being had to the accompanying drawings, forming part of this specifimtion.

My invention has been designed more particularly with reference to use as an attachment to a well-known adding-machine now upon the market and in general use, commonly called the Burroughs Registering Accountant, which machine will be found illustrated and described in Letters Patent of the United States of America, No. 504,963, granted September 12, 1893, upon the application of William S. Burroughs. As will be understood from the explnnation of my inventionhereinmtergi ven, however, its utility is not restricted to its use as an attachment to this Burroughs machine; but on the contrary, it may be employed in connection with other suitable machines of a different construetion.

The principal object of my inver tion is to provide an improved paper carrying and feeding attachment for machines of this eharactor which will accommodate rolls or sheets of paperof any desired width and permit them to beadjusted laterally to dill'erent positions for the printing of vertical columns of numbers thereon at any desired pointin the width of the roll or sheet.

A further object of the invention is to provide means for readily separating at will the feed-rolls by which the paper is advanced to .permit the ready insertion and adjustment of the-paper, particularly where several sheets are employed with interposed carbon-paper for manifolding purposes.

Referring now to the acmnnpnnying drawings, Figure 1 represents a side elevation of the attachment, embodying my invention; Fig. 2, a middle vertical section: F lg. 22, 3 rear elevation with part oi't-lie bow-innuelzromr'n awa Fig. 4, a top plan vii-n": l"'! 5, a. transverse sectionaldetail view; and Pi". 6, a perspective view of the paper-holder.

The same letters of reference are used to indicate identical parts in the several views.

In the Burroughs adding-machine, heretofore referred to, the paper strip or sheet upon which the printing is clfected is forward between a pair of feed-rollers located attherear end of the machine, and thence upward over the upper one of said rollers, the latter serving also asa plcten-rollcr, upon which the types elfcct the printingas the paper passes over the faeeof such roller. When my invention is employed as an attachment to the Burroughs machine, the two rollers A B take the place of the two rollers above re- 1' erred to, and the upper roller A constitutes the printing or platen roller whose forward face receives the impact of the type, the attachmeut being secured to the rear end of the machine. In the Burroughs and other similar machines the two rollers A B are jours nalcd at their opposite endsin a supportingframe in such a manner that the sheet or strip of paper can be inserted between them only from their front or rear sides, and con seqnently they cannot accommodate paper of greater width than the length of the rollers themselves.

The first feature of my invention consists in supporting the two rollers A B one above the other in such a way that a strip or sheet of paper of any width can be inserted laterally between the rollers and adjusted lengthwise thereof to any desired position. To this and the lower roller 3 is journaled in the upper end of an upright frame 0, adapted to be seem-rd in fixed position upon the rear end of the adding'machine, the lower end of the [mine being provided with transverse holes 501;, adapted to fit upon a fixed rod present i u the Burroughs machine and shown in the Burroughs patentbefore mentioned. The frame C is further secured tethe rear end of the :iddingmachine by suitable means. (Not shown.) The upper roller A is supported above the roller 1 by means of a. bow-frame l, whose lower forward end is secured to the frame C and whose npper forward end has seen re;l to it a fixed cross-piece E, upon which rests a yoke-frame F, in whose forwardlyproje-cting arms F is journaled the roller A. The frame F is connected to the cross-piece E by means of thumb-screws G, whose threaded lower ends pass freely through holes in the horizon tal plate of the frame-F and screw into threaded holes in the cross piece E, Fig 5. The heads of the thumb-screwsG do not bear directly upon the plate F, but upon .thick rubber washers H, interposed between them and said plate, so thatfwhen the screws are tightened up the plate F is securely but yieldingly held to 'the'cross-piece E. The

V adjustment of the parts is such that at such to be forced time the roller A-wlllbe pressed into firm contact with the roller B, cooperating with it for the purpose of advancingthe paper strip when the rollers are-tn rned. The yielding connection ofthe roller-frameF with the cross-pi'ece'E, however, permits the roller A upward slightlyaway from the roller "B for the ready insertion and adj ustment of vthe paper. As a means for thus separating the rollers whenever desired there is provided a lever I, fulcrumed upon the up per side of the plate-F, midway of its length,

- Fig. 4, and provided upon the under side of its front end with a stud I, adapt-"ed when the rear end of"theleveris. forced to the left to ride, over an inclined surface 1" upon the upper face of the cross-piece E, Figs22, 4, and

5, and thereby force the frame F and roller A slightly upward against the resistance of the rubber springs H, interposed between the heads of the screws G and the frame F. By

pressing,the rear end of the lever'[ to the one side, therefore, the rollers A B may be separated at any time to permit the ready insertion and adjustment of; the paper, and upon throwing the end of the lever back ,to normal position the frame F will-be released and the springs G will force the roller A toward the roller B again and grip the sheet ofpaper between them; a I

For the purpose of advancing-the paper at each operation of the machine the spindle-of the lower roller B has secured to it a ratchet J, with which cooperates a pawl K, pivoted, upon the rear end of a lever L, fulcru med at M upon the side of theframe 0. Depending Ire mtthe lever L in rear of its fulcrum is an arn. L, through which is passed a stop-screw L", Fi gs. 1 and 3, whose forward end contacts with therear edge of a-plateN, securedto the side of the frame 0, and limits'the downward movement of therea'r end of the face P, with which cooperatcsa roller 538 upon? the upper end of the lever 513. (Shown and described in the Burroughs patent, No. 504,903, heretofore referred to.) The upper end of this operationof the machine vertical portion of the bar lever 513 is thrown rearward a definite (listnnce at each operation of the machine, and the roller 538 rides over the incline surface 7c P on the end of the lever L and rocks the latter, pressing its front end downward and throwing its rear end upward and'causing the pawl K to turn the roller B and advance the paper passed between said roller and the 7g roller A. The engagement of the roller 588 with the lever L will throw the rear endof said-lever and pawl K upwardeto a certain position at each -operation of the machine, and by adjusting the stop-screw L to cause the lever and pawl normally to occupya lower or a higher position the lever'maybe givenal greater or less degree of; movement at each to advance agreater or less length of paper, as may bedesired;

'As' so far described my attachmentwould' be complete for use with loose sheets of paper of any desired width, the unused portion of the paper (if of considerablelength) being curledup ina roll within the bow-frame D, go behind the frame 0 and rollers AD, or, when desired, the unused portion of the paper may be held in the holdershown in Fig. G, said holder consisting of a bar Q, having secured, to, its upper side a series of curved wires R, 5 and the latter in the-present insiancehaving secured to their forward sides a curved guardplate S. The bar Q of this holder is adapted to fit and slide lengthwise in a dovetailed guideway T, which ,nmy be secured-directly to the bow-frame D, but in the present instance is carried by the rear end of a bracket: plate U, secured'at its forward end to the frame'C and extending rearward therefrom immediately -over the lowerhorizontal porr05 .tion of the bow-frame D.

Where the printingis to he eifectedhpon a long strip of paper carried in a supply-roll, the latter will be mounted upon .the spindle V, carried by the vertically-bent end of a bar vi to W, whose lower horizontal portion is shaped to engage and slide longitudinally in the guideway T. From the roll upon the spindle -V the paper strip passes forward beneath a guide-bar X,secured at'therear end of its rear- 1 r5 wardly-projecting arm to theupper end oi the V W, and thence up.- ward over the rear s'ideof the roller B, and onforward between the said roller and the upper roller A, and upward over the forward no side of the latter. To guide the paper'over the forward side of the roller A, there is'pr'o vided aframe' Y, to whose crossbar are-secured several pairs of curvedfw'ires Z, extending upward and rearward over the forward face '01 the roller A. I

For the storage oft-he printed portion of the paper strip there is provided a reel A, mounted in a bracket-frame B, detachably secured I to thcnpperrear side of the bow-frame I), Fig. 4, and provided with a handle 0, by

which it may be turned to wind up the printed portion of the strip delivered from the rollers A l A wire E, secured at its lower forward end to the side of the bracket-frame it, is suitably bent i nward and rearward and shaped to press against the roll of paper wound upon the to" A and produce the necessary f riction upon said roll to prevent the paper from becoming unwound.
